2. Description
Utilization
Dehumidifiers in accordance with the absorbtion principle are used to solve drying problems in the
process technique, in the climate technique, at construction sites and to dehumidify production and
storage rooms, in which products and facilities require a very low air humidity. The dry unit U-7002
with humidity control U-7100 is specifically designed for use in large dry storage cabinets and dry
rooms. The dry unit operates without interruption. The drying unit U-7003 differs from the U-7002
through an additional reheating. The heat output and temperature is controlled and monitored by the
control unit U-7100.
Operation requirements
Totech air dehumidifiers are in general deployed with beginning conditions of 20°C at 60%r.H. With
diminishing relative humidity the process air and/or increasing relative humidity of the regeneration air
the dehumidifying performance is affected negatively.
A) The air dehumidifier should only be used with surrounding temperatures
between -20°C und +40°C !
B) The temperature of the process air sucked up should at most be +40°C
and the temperature of the regeneration air should at least be -15°C !
C) The air sucked up may not contain free water (water drops) !
D) Air dehumidifiers should not be deployed in liquids or should not suck up
liquids (f.i. full tanks or tubs, flooded surfaces etc.).
E) The operation in and/or with explosion sensitive atmosphere is only
allowed for apparatuses typified by RL 94/9/EG (Atex 95). The owner is
obliged to check the deployment of the air dehumidifier according the RL
1999/92/EG (Atex 137) !
F) When putting into operation with contaminated air "Damaging Influences
on Rotors " should absolutely be observed !
